Pulse Oximeter

Pulse Oximeter
pulse oximeterA pulse oximeter is a medical device that measures the oxygen level in your blood and your pulse rate. The oximeter that we use on Kilimanjaro is placed on a climber's fingertip. The oximeter uses two beams of light that shine into small blood vessels and capillaries in your finger. The sensor reflects the amount of oxygen in the blood.
Oxygen saturation is a measurement of how much oxygen your blood is carrying as a percentage of the maximum it could carry. Normal blood oxygen levels at sea level are 95-100%.
